In one embodiment, a contactless portable consumer device which includes a first antenna is shielded from unauthorized wireless interrogation with a radio frequency (RF) shield. The RF shield includes electrically conductive, non-ferromagnetic material and is configured to prevent unauthorized data transfer between a second antenna external to the portable consumer device and the first antenna."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method to electromagnetically shield portable consumer devices","description":"An apparatus and method is provided to shield contactless portable electronic consumer devices such as radio frequency identification devices (RFID), tokens, mini-cards, key fobs, cellular phones, sma","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9704087","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
